Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.76 g/mol gives 2-Chloro-N-(3-cyano-4,5,6,7-tetrahydro-1-benzothien-2-yl)propanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-N-(3-cyano-4,5,6,7-tetrahydro-1-benzothien-2-yl)propanamide (CAS 351013-92-8), molecular formula C12H13ClN2OS and molecular weight 268.76 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-N-(3-cyano-4,5,6,7-tetrahydro-1-benzothien-2-yl)propanamide (C12H13ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-Chloro-N-(3-cyano-4,5,6,7-tetrahydro-1-benzothien-2-yl)propanamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
